The crank shaft 2 6 has an eccentric wristpin 30 which works in the bearings 3| on one end of the connection rod32. The other end of this connecting rod has a bearing 33 which islocated between the bearings 34, 34 formed on the upper ends of theupwardly extended arms 35, 35 formed integrally with, or attached to,the yoke 9. A common cross-pin 36 is fitted through the aligned bearings33, 34. The range of travel of the yoke and the pistons 0n the pistonrods 1, is thus determined.

The drawings and description are illustrative merely, while the broadprinciple of the invention will be defined by the appended claims. WhatI claim is:

1. An internal combustion motorcomprising oppositely arranged cylinders,a shaft arranged perpendicular to the axis of the respective =cylinders,pistons reciprocable in the cylinders, a yoke having rack faces, pistonrods connected to the yoke and to the respective pistons, meansoperatively connecting the yoke with said shaft and :spective pistons,means operatively connecting the yoke with said shaft and efiective totransmit rotation in a constant direction to the shaft as the pistonsreciprocate, a crank shaft mounted to rotate on the motor and having aneccentric wrist,

a connecting rod one end of which has a bearing V on said wrist, anupstanding arm on the yoke to which the other end of the connecting rodis connected.
